Question PLEASE NEED HELP for brainliest:( a square – b square=12 (a-b) square = 9 what is a square + b square

Answer: a² + b² = 25/2 Step-by-step explanation: a² – b² = 12…….eq(1) (a – b)² = 9……..eq(2) From eq(2), (a – b)² = 9 (a – b) = √9 (a – b) = 3………eq(3) Making “a” subject formula in eq(3), we have a = b + 3…………eq(4) Substituting eq(4) into eq(1) a² – b² = 12 (b + 3)² – b² = 12 (b+3)(b+3) – b² = 12 9+3b+3b+b²–b² = 12 9 + 6b + 0 = 12 6b = 12–9 6b = 3 b = 3/6 b = 1/2 To find “a” from eq(4), when b=1/2 a = b+3 a = 1/2 + 3 a = 7/2 Therefore, a² + b² = (7/2)² + (1/2)² = 25/2 To check if the values of “a” and “b” is correct, from eq(1) and eq(2) a² – b² = (7/2)² – (1/2)² = 12 (a–b)² = (7/2 – 1/2)² = 9 Reply
